Carbon dioxide (CO2) geological storage is the last process in carbon dioxide capture and storage (CCS). Technical issues to conduct it safely are firstly introduced. Geophysical and geochemical trapping mechanisms to store CO2 within the reservoir, geophysical monitoring and modeling, and geomechanical modeling are then described as key issues. Finally, future directions are discussed.

Carbon dioxide (CO2) geological storage is the last process in carbon dioxide capture and storage (CCS). Technical issues to conduct it safely are firstly introduced. Geophysical and geochemical trapping mechanisms to store CO2 within the reservoir, geophysical monitoring and modeling, and geomechanical modeling are then described as key issues. Finally, future directions are discussed.
